林兹蛋糕（德语：Linzer Torte）是源自奥地利、有着网格花样的甜点。

于17世纪期间林兹蛋糕便有出现在历史文档的纪录，在2005年北奥地利博物馆图书馆长及同为《如何制作林兹蛋糕》（Wie mann die Linzer Dortten macht）一书作者的瓦尔特劳德（Waltraud Faißner），有在阿德蒙特一带的修道院图书馆Admont Abbey里找出存在于1653年的调理文档，在此之前是所能发现最早版本的配方。

此甜点会被称为林兹的起因未有明确说法，有一说是一位名为约翰·康拉德·沃格尔（Johann Konrad Vogel）的19世纪点心师傅在奥地利林兹一带地区将此类型甜点给热卖、而随后被顺势冠上当地名称。

The Linzer Torte (or Linzertorte) is an Austrian torte with a lattice design on top of the pastry. It is named after the city of Linz, Austria.

Linzer Torte is a very short, crumbly pastry made of flour, unsalted butter, egg yolks, lemon zest, cinnamon and lemon juice, and ground nuts, usually hazelnuts, but even walnuts or almonds are used, covered with a filling of redcurrant jam or, alternatively, plum butter, thick raspberry, or apricot jam. It is covered by a lattice of dough strips. The dough is rolled out in very thin strips of pastry and arranged to form a criss-cross design on top of the preserves. The pastry is brushed with lightly beaten egg whites, baked, and sometimes decorated with sliced almonds.
